Streptococcus lactis subsp. cremoris (Orla-Jensen) comb. nov. and Streptococcus lactis subsp. diacetilactis (Matuszewski et al.) nom. rev., comb. nov.

Abstract

Streptococcus lactis (Lister 187) Lohnis 1909 and Streptococcus cremoris Orla-Jensen 1919 have a number of significant properties in common and belong to the same DNA homology group. S. cremoris is here regarded as a subspecies of S. lactis. The name of the subspecies is S. lactis subsp. cremoris (Orla-Jensen) comb. nov.; Streptococcus diacetilactis Matuszewski et al. 1936 does not appear on the approved lists of bacterial names. However, it is here regarded as a recognizable taxon, for which the name S. lactis subsp. diacetilactis nom. rev., comb. nov. is proposed. The type strain of this subspecies is NCDO 176.
